/* Общие стили внутренних страниц сайта Plum: страница взрослого (/roditelyam/) и документы (/dokumenty/…).
   Та же ледяная студия, что на главной: лёд, матовое стекло, цвет несёт только Plum и кнопка. Шрифты — свои (fonts/fonts.css).
   Тон взрослый и спокойный: заголовок страницы — фирменный капс, всё остальное — Onest, крупно и с воздухом. */
